Community builds that use it

BabyNo level-up stats, so all stats come from the shop; Sticks are the standard choice because base damage grows with each Stick held, and survivability needs Armor, Dodge and Max HP. XP Gain items and a broad mixed melee loadout are alternatives.
ChunkyMax HP is both defence and damage, so stack Max HP and Armor and heal through consumables; Chopper, Spiky Shield, Rock and Pruner are the recommended weapons. Speed upgrades do nothing, which makes items with a Speed penalty attractive.
MasochistGetting hit adds % Damage, so tank hits with Armor, Max HP and HP Regeneration; Spiky Shield (unlocked by winning with Masochist) is the main recommendation, with Scissors, Ghost Axe or Medical Gun as alternatives. Blood Donation or Bloody Hand trigger the passive every second.
OgreKills explode and the explosions scale with Max HP, so stack Max HP and Melee Damage; Brick, Rock, Chopper and Fist starts are recommended, moving to Spears or Trident for long-range triggers. Keep Speed positive despite the Blunt and Ogre penalties.
